Afterward, we will create an angular application from scratch and build a beautiful file-upload component using the angular material ui-component-library.

Before we can start writing our angular file-uploader, we need to have an API to upload to right? In this tutorial, we are going to create a simple node. The first one is obviously express. Express is a framework, that makes creating API very easy. To install express, you can use this command. Because we want to access the API from an angular application, the server needs to allow cross-origin requests.

Therefore we are going to use a simple module called CORS. To install it, type:.

Also, express itself is not very good at understanding forms. Install formidable using this command:.

First, we need to create a basic express server in the server. This part looks always the same and consists of only 3 lines. This is already a working express server. Although it is not doing anything useful, we could start it using the. To be able to access our API from an angular application, we need to enable cors. To do so, we first need to require CORS.

After that, we need to export the callback function, we are using in our server. This callback gives us a request-object req , that stores information about the request that hit the route. We then register callbacks on that form. The first callback is called for every file in the form:. The uploaded files are stored in a temporary directory somewhere on your machine.

To do something with them, you can copy them from there using the node. The second callback is called when the form is completely parsed. In this case, we want to send back a success status code. It is not production ready, but it will help us to test our upload-component of the angular application we actually want to build.

Now that we have a working API we can code against, we can start creating the actual file-uploader. For that, we first need to create a new angular project. We are going to use the angular-cli for this project. Create a new application by opening a command prompt at the desired location and type:.

Because we will need some complex ui-elements such as modal-windows, I decided to use the angular material library for this project. To install this library, use this command:. Also, we are using a flexbox-design for this. Install the library like this:. To make our desired file-upload component as re-usable as possible, I decided to bundle it into a separate feature module.

Next, we will need to import a lot of external modules into this new module. For example, we need to import all the angular material ui-components we are going to use. Notice, that we are also exporting the UploadComponent, to make it available outside of this module. Before we can create the visuals of our file-uploader, we first need to implement the upload logic.

The Challenges

This logic will be placed in the UploadService. Create that service inside of the upload directory. Just use this command:. Inside of that service, we need to use the HttpClient , so we request it using dependency injection. This upload method will return a map of progress objects. One for every file to upload. This object contains a observable of type number because it contains the progress of the upload in percent.

MODERATORS

Inside of the upload-method, we package every file into a form, create an HTTP-post-request and send away that request with the form as payload.Source 3 If we look at this example from the same Rangle guide we can see that the Subscription to route.

As soon we've selected a file we're setting our form value for our avatar to an object which contains the filename, the filetype and the value which is the base64 encoded string! Express is a framework, that makes creating API very easy. For example, we want to close the dialog from the dialog component. We will also need some state variables in the future, so we should add them to our DialogComponent. First of all we're going to need a model for our user: There's no magic in this file, but if you haven't read the article about Reactive Forms you should probably do that before.
